Take a look at the following pictures of my lens - I took them in front of a table light.

It's an old Soligor lens so I expect and have always seen some dust - but on really close inspection I think I have something else going on.
Before I took these pictures I cleaned the front and back glass with a "micro fiber" cloth.

In this picture, is that haze on the perimeter between 6 o'clock and 9 o' clock?

Here's another one from a similar angle.

Other side looks much cleaner...

I'm also concerned about the spot at around 8 o'clock in this picture. Is that fungus?
